I use org-mode, with auto-capitalize-mode turned on.

But sometimes, within org-mode, I want to type out some lisp, highlight it, and execute it.

I might type something like

(setq org-cycle-emulate-tab)

Auto-capitalize automatically capitalizes setq to Setq.

I don't feel like switching modes to emacs-lisp-mode or disabling auto-capitalize-mode. I just want it to recognize that I never want the word setq capitalized.

How can I disable autocapitalization for certain specific words?

  • I think that modification is a list of words for which the NEXT word should not be capitalized, e.g. the word AFTER "e.g." should never be capitalized. But I want a list of words that should THEMSELVES never be capitalized. Oct 27, 2015 at 17:47

    Lines 61 to 63 of the comments in the source code -- github.com/yuutayamada/auto-capitalize-el/blob/master/… -- state: "To prevent a word from ever being capitalized or upcased (e.g. "http"), simply add it (in lowercase) to the `auto-capitalize-words' list."

  • So like this? (setq auto-capitalize-words '("I" "setq")) Oct 27, 2015 at 18:19

    I answered with eval-expression ( M-: ) but the OP said " another reason I often type setq in an org-mode environment is to change my config. I keep my Emacs config in org-mode files, inside source code blocks. I can do <kbd>C-c '</kbd> to enter the source code block, but sometimes I just want to quickly type in a setting without entering the block."

The doc-string for the variable auto-capitalize-words states as follows: "If non-nil, a list of proper nouns or acronyms. If 'auto-capitalize' mode is on, these words will be automatically capitalized or upcased as listed (mixed case is allowable as well), even in the middle of a sentence. A lowercase word will not have its casemodified." [Admittedly, the comments in the source-code, infra, are more concise than the doc-string itself.]

Lines 61 to 63 of the source-code -- https://github.com/yuutayamada/auto-capitalize-el/blob/master/auto-capitalize.el -- contain comments that state: "To prevent a word from ever being capitalized or upcased (e.g. "http"), simply add it (in lowercase) to the 'auto-capitalize-words' list."

The original poster has confirmed (in the comments underneath the original question) that the following setting resolves his issue:

(setq auto-capitalize-words '("I" "setq"))
  • This works for lowercase words like setq but it doesn't respect mixed-case words like iPhone. How do I add the word "iPhone" to auto-capitalize-words so that auto-capitalize-mode respects its case? Oct 27, 2015 at 20:13
